Dewalt DWA4971 Abrasive Bur SL-5D Conical Radius End

Product Description

The DEWALT DWA4971 is a high speed steel abrasive bur with an SL-5D industry specification and a conical radius end (taper) head shape. It features a rasp tooth style for aggressive material removal in metal, wood, and composite surfaces. The 1/2-inch cutting diameter and 1/4-inch shank diameter make it compatible with standard die grinders and rotary tools. At 0.075 pounds, the bur is lightweight for extended use. The uncoated high speed steel head delivers durability across a range of grinding and shaping applications common in fabrication, HVAC ductwork, and mechanical trade work.

This abrasive bur is suited for use in metal fabrication shops, HVAC installations, plumbing rough-ins, and general mechanical service environments. The SL-5D specification designates a taper-style bur commonly used for deburring, shaping, and enlarging holes or ports in ferrous and non-ferrous materials. The rasp cut is well matched for fast stock removal on softer metals, plastics, and wood composites. Trade professionals in HVAC, plumbing, and electrical work use this type of bur for fitting and finishing tasks where precise shaping is required.

Key Features

• SL-5D industry specification with conical radius end (taper) head shape for precise material shaping
• Rasp tooth style for aggressive, fast stock removal
• 1/2-inch cutting diameter provides a wide working surface for deburring and port shaping
• 1/4-inch shank diameter fits standard die grinders and rotary tool chucks
• High speed steel construction, uncoated, for use across ferrous metals, non-ferrous metals, and composites
• Lightweight at 0.075 pounds for reduced fatigue during extended use

Compatibility

Designed for use with standard 1/4-inch chuck die grinders and rotary tools. Suitable as an OEM-style replacement or direct addition for any setup requiring an SL-5D conical radius end rasp bur with a 1/4-inch shank.

Installation Notes

Installation is performed by machinists, fabricators, and trade professionals using a die grinder or rotary tool with a 1/4-inch collet or chuck. Always power down and disconnect the tool from its power source before installing or removing the bur. Secure the shank fully in the collet and tighten per the tool manufacturer's specification before operation. Wear appropriate eye protection and gloves when operating rotary abrasive tooling.
